Clark, Engineer and I have posted on this. You are not getting it. Let me explain this mystery to you: it is called Shannon's theorem. To simplify it for you, less interference (or noise) leads to more capacity. The power-control signaling overhead for IS-95 based WLL and IS-95 based mobile are EXACTLY the same (1 bit every 20ms). But because the WLL channel condition is benign (compared to the mobile channel) the same bits are better able to track the channel, leading to less interference hence more capacity (there are a couple of other things in addition, but lets leave them 'till you understand the simpler concepts). If you are not already working for Ericcson, may I encourage you to apply to them? Perhaps they would value the unique combination of lack of CDMA knowledge and arrogance you bring to this thread? Regards.
